Dover sole is mild and sweet in flavor with a thin flaky meat. This fish is prone to overcooking as it’s a thin fillet like most flatfish, so wet cooking methods are recommended for new chefs. U.S. wild-caught Dover sole is a smart choice as its sustainably managed and responsibly harvested under U.S. regulations. Dover sole is found in the Pacific Ocean from the Bering Sea and western Aleutian Islands to southern Baja California.
